Fig. 7. Cell proliferation activity after 1, 3, and 5 days of culture in different resin extracts. (A) L929 cell morphology and number after 1, 3, and 5 days of culture. (B) Relative growth rate of L929 cells after 1, 3, and 5 days of culture. Asterisk indicates statistical difference from TM0 group. (C) Relative growth rate of L929 cells after 1 day of culture at different concentrations of resin extracts. (D) Real-time monitoring of L929 cells infected with different resin extracts using RTCA system. At indicated time point, cells were inoculated with serial resin extracts.
